Widespread Panic's Gear
The type of glue a builder uses can make a big difference in their process, but when it comes to tone, does it matter?
Guitarists searching for their ultimate instrument are an interesting bunch. So many factors to consider, so much energy to expend on the journey towards guitar nirvana. A player may be satisfied with a certain shape—like a Flying V or Explorer. Others are obsessed with pickups, hardware, fretboard radius, scale length, or fret size. I’d venture that most of us consider a lot of these things and more when choosing a guitar. But there is a certain place in my heart for those infatuated with the type of glue used to construct a potential purchase. Don’t get me wrong, I’m not listening to Ford Thurston and thinking what he needs is a little more hide glue in his tone, but somebody might be. This obsession probably stems from the mythology of vintage instruments more than any sonic observations.
Instrument makers have used animal-based glues for centuries, mainly because it was all that was available. Adhesives can be made from a variety of animal remains: bones, hooves, hides (skins), and even fish parts. These organic items are basically proteins that can be boiled down to a gel-like substance which, when heated, becomes sticky, spreadable, and can be used to bond a wide range of materials, including wood. For this discussion, I’ll refer to all of these as hide glues.
Woodworkers used hide glues almost exclusively until the middle of the 20th century, when synthetic glues became available. Adhesives such as PVA (polyvinyl acetate) are sometimes referred to as yellow or white glue. Over time, and as instrument building became more of an industry as opposed to a boutique craft, PVA became the standard in large-scale commercial instrument manufacturing.
Industrial PVA glues dry quickly, are extremely shock resistant, and do not require heat. They have nearly no odor, and they can be stored ready to use for long periods of time. They are also incredibly strong. Unlike hide glue, which requires a precise parts fit, PVA is gap-filling which is great for factory tolerances. PVA’s setup time is short, and under some circumstances, clamps can be removed in as little as an hour. That certainly allows more production to flow through a factory or shop.
“Hide glue is very brittle when cured, which has led some to say that it encourages the transmission of vibration from part to part.”
On the other hand, hide glues need to be warmed in a heat pot to around 140° F, and have a shorter shelf life at room temperature. Although some builders learn to love the smell of hide glues, others find it revolting. I don’t mind the smell, but some don’t want the “dead animal” smell on their clothes. Hide glue can also have a shorter “open” time before it locks up, which doesn’t allow for much adjustment to parts during assembly. Additionally, once clamped, hide glue needs to remain so for much longer—most shops let it dry at least overnight.
I believe that a lot of the mystique stems from old-school repair people who would prefer to work on older instruments constructed with hide glues, which are easier to disassemble. A distinct advantage is that unlike PVA, epoxies, and superglues, hide glue can be easily loosened for repair with heat and water. That’s a real bonus for shops that specialize in neck resets, fretboard replacements, and all manner of acoustic guitar repair. Old hide glue can be successfully removed from a joint and new glue can be applied for a repair—as the new glue will bond directly to old glue.
Another characteristic of hide glue is its self-clamping action when the fit of parts is very tight to begin with. The glue pulls parts together as it dries and can be good for jobs like book-matching tops and backs—even without clamps. Hide glue is very brittle when cured, which has led some to say that it encourages the transmission of vibration from part to part. This, along with the tight fit aspect, may be the primary source of the “hide glue is better” sentiments that get repeated as gospel in some circles. Of course, if you leave your hide-glued guitar in a car trunk on a hot summer day, you may regret it as much as the repair shop loves it.As you can see, there are a lot of benefits to each of these glue types, and I haven’t even gotten into any discussion about epoxies or superglues, which are being used more and more frequently today, along with so-called hybrid hide glues. The question remains, is the adhesive used in building a guitar a deal-breaker? As much as I admire instruments built with old-school glues, I’m not sure Ford Thurston or I could hear the difference. And if that particular guitar does sound wonderful, I couldn’t say it was because of the glue. Besides, with its 1-piece neck and four-screw neck joint, a Stratocaster doesn’t have use for a lot of glue anyway.
Never kit-built a stompbox? It’s easy—if you let pro pedal maker Alex Guaraldi of CopperSound be your guide. Here, he takes you on a step-by-step tour as he assembles a Build Your Own Clone Classic Delay.
For this DIY adventure, we’re going to be walking through the steps of building the Classic Delay pedal from Build Your Own Clone (BYOC), a company that has been a big player in the pedal-kit game for quite a while. This is a little more complicated than building a fuzz or overdrive, so I’m going to explain the process with great detail. Let’s get started.
Tools You’ll Need for This Project
- Soldering Iron
- #2 Phillips screwdriver
- Wire strippers
- 8 mm (5/16") nut driver/wrench
- 10 mm (25/64") nut driver/wrench
- 1/2" nut driver/wrench
- 14 mm (9/16") wrench
- Flush cutters
- Small needle-nosed pliers
- Third hands
These tools are available via a variety of suppliers, including StewMac, Allparts, and Amazon.
Step 1: Review the Instructions
The kit as it arrives (Photo 2).
Each BYOC kit comes with a detailed set of instructions in the form of a PDF that can easily be printed out. The Classic Delay’s instructions can be found at http://www.byocelectronics.com/classicdelayinstructions.pdf. They are 32 pages long, and I suggest following their steps as you read this article. Here, I will refer to specific page numbers that correspond with the steps. I’ve also taken photos to coincide with the steps. Within the instructions, we find a table of contents, pictures of the fully assembled pedal, a list of parts included, and step-by-step instructions from internal population and soldering to external assembly. With any kit, always read the instructions carefully before you start building.
Step 2: PCB set-up
A lot of pedal builders use PCB jigs that are specifically designed to hold several printed circuit boards so that they can be easily populated and soldered. These jigs are great tools. However, they’re not something a casual DIY enthusiast will often have. Essentially, all we really need to do is elevate the PCB off of the working surface so that the leads of the components can pass through the bottom side of the PCB. This is most helpful with components that can be soldered from the top side of the PCB. “Third hands” or “helping hands” (Photo 3) are a good tool for this job. So, what can we do to elevate the PCB if we don’t have access to third hands? Simply turn the enclosure upside down and place the PCB perpendicular (Photo 4). This will elevate the PCB enough to allow the component leads to easily pass through.
Step 3: Populating Resistors and Diodes (instructions page 9)
When populating PC boards, we typically like to work lowest to tallest in regards to the seating. Seating is how far above the PC board the component rests. Resistors and diodes sit pretty low to the PC board, so populating them first makes sense.Resistors: Remove the resistor from the paper ribbon, bend the leads (Photo 5), and place them through the corresponding pads (Photo 6) as directed. (A pad, by the way, is the term for the designated surface area of a component’s electric contact point.) A good practice is to populate all resistors of the same value before moving on to the next value. Populate all 1k resistors, then all 10k resistors, and so on.
Reading resistor color bands can be confusing, so don’t forget the reference guide on page 7 of the instructions. Here, you will find a detailed breakdown of each value and its corresponding 5-band reading (i.e. 1k = brown/black/black/brown/brown). Once all the resistors are placed, we can go on to the diode.
Diode: Next, we need to place the diode. Just like resistors, remove the diode from the paper ribbon, bend the leads, and place them through the corresponding pads. Diodes are polarized and need to be oriented a certain way (Photo 7). Be sure to match the diode to the outline on the PCB, as shown on page 10 of the instructions.
Step 4: Solder Resistors and Diode
Fire up the soldering iron! Once the iron is up to temperature (650 to 750 degrees Fahrenheit, depending on how fast you work), it’s time to get to work. Resistors and diodes can easily be soldered from the top side. So no need to flip the PCB over. Place the solder tip to the pad and feed the end of the tip a bit of solder. What we’re looking for here is solder that covers the entire pad, encapsulates the lead, and has a nice shine to it. Think of it like a shiny Hershey's Kiss shape (Photo 8). Repeat this step for every part. If you’re new to soldering, you should consult our concise guide to soldering, online or in PG’s October 2015 issue.
Soldering tip: Shut the iron off between population steps. Use a small, tabletop fan to blow the solder fumes away during soldering steps. Quick tutorial videos on YouTube are also of benefit here, for builders new to soldering.
Step 5: Trim the Leads
Next, place the PCB upside down to expose the leads (Photo 9). Using flush cutters, trim the excess leads (Photo 10).
Step 6: Soldering IC Sockets (page 11)
Place the 8-pin and 16-pin IC sockets into the corresponding pads on the top side of the PCB. We need to solder the IC socket pins from the bottom side. This means flipping the PCB over without having the IC sockets fall out. For this, I like to use a small piece of foam (Photo 11).
I place the foam on top of the PCB (Photo 12), then flip the foam and PCB simultaneously so the foam is below the PCB and the bottom side of the PCB is facing up (Photo 13).
For this soldering step, we’ll want to solder ONLY 1 pad and then flip the board over to ensure that the IC sockets are sitting flush. If the IC sockets are not flush, go back to the bottom side and reflow that solder pad while pressing the PCB downward and keeping it parallel to the work surface. Solder the remaining pads (Photo 14).
Step 7: Soldering the Voltage Regulator (page 12)
Place the voltage regulator into the three corresponding pads, while keeping mindful of the orientation. The flat side needs to match the outline on the PCB. Now, we’re ready to solder. This can be done from either side. Flush-cut the excess lead and we’re done here (Photo 15).
Step 8: Soldering the Trim Pot (page 13)
Place the trim pot (Photo 16) into its corresponding pads. For the trim pot provided, I found it easiest to solder the two exposed legs from the top side (Photo 17) and then the remaining leg from the bottom side.
Step 9: Soldering Ceramic and Film Caps (page 14)
Place all ceramic (pill-shaped) and film (red) caps into their respective locations. Again, use page 7 of the instructions as a reference for identifying the correct capacitors (i.e. 100n film cap, which may say “104” or “.1” or “u1” on the body). We’ll need to solder the pads from the bottom side. So, once again, the piece-of-foam trick can be your friend here. Flush-cut the excess lead and we’re done (Photo 18).
Tip: An alternate method would be to bend the leads away from each other so they stay in place when the PCB is flipped over (Photo 19).
Step 10: Soldering Electrolytic Caps (page 15)
Let’s do the same thing here as we just did in Step 9. One thing to note is that electrolytic capacitors are polarized and need to be populated in the correct orientation. This is denoted on both the PCB and the component itself. On the PCB, the positive pad is denoted by the square pad. On the electrolytic capacitor, the positive lead is the longer leg. Additionally, the negative lead of the cap also corresponds to the white strip on the body (Photo 20).
So, let’s go ahead and populate the caps and solder them with either the foam trick or by bending the leads. Flush-cut the excess lead and we’re done (Photo 21).
Step 11: Battery Snap and Hook-Up Wire
This DIY kit offers a battery option for those that feel so inclined. (See page 17 of the instructions.) For this step, we’ll need to connect the battery snap to the PCB. Before soldering, we’ll want to first feed the two wires through the holes directly below the solder pads. These holes act as strain relief for the battery snap and have + and - signs next to them (Photo 22). Then, simply solder the red wire to the positive (+) pad and the black wire to the negative (-) pad (Photo 23).
Next, we need to cut and strip the included wire (page 18). We need four 2.5" pieces of wire, and one 1.5" piece (Photo 24).
Place the 2.5" wires into the top side of the solder pads for in, out, and the two courtesy grounds—all handily marked. Then, solder from the bottom side. Do the same for the 1.5" wire going to the ring pad (Photo 25).
Tip: If painting the enclosure is desired, this is the last chance you’ll have to do it. After this, there will be components mounted to the chassis.
Step 12: Install DC Jack (page 19)
Place the DC jack into the large hole on the back heel of the enclosure and tighten the nut using a 14 mm (9/16") wrench (Photo 26).
Step 13: Potentiometers and Status LED (pages 20 and 21)
The included instructions for this next part have you mate the PCB to the inside of the enclosure. This will help line up the pots and LED. However, afterwards it will make soldering the remaining wire more difficult. Here’s a trick we can do that gives us the benefits of using the enclosure to help with pot alignment without needing to take the PCB out afterwards to solder the remaining wires. What we’ll want to do is simply use the face of the enclosure to hold the pots and set the LED height. Additionally, we can use the flush cutters to help balance the PCB (Photo 27). Be sure to have the long lead of the LED mate with the square pad, then solder away!
Step 14: Final Hook-Up Wire
My steps continue to vary slightly from the instructions throughout the rest of the build, so you might want to do a side-by-side comparison. Let’s finish the wire for the DC jack next. Cut and strip three 1.5" pieces. These need to be placed into the three power pads at the top of the PCB marked -, +, + , as in Photo 28.
Next, cut and strip five more 1.5" pieces. Place these in the footswitch pads at the bottom of the PCB marked 1, 2, 5, 7, 8 as shown in Photo 29.
Last wire! Cut one 1.5" piece. Only for this one, strip half an inch off of one side (Photo 30). Place the short-stripped side into the footswitch pad labeled 4.
Step 15: Footswitch prep
For the footswitch, we need to jump lugs 3 and 6. To do this, we’ll use the remaining wire. Place the footswitch into the correct hole on the face of the enclosure. Then, cut a 1" piece of wire and strip half of it. Feed the exposed wire through lug 3 and into lug 6 and then solder both (Photo 31). Cut the excess wire.
Step 16: Insert the IC
Now, we’re ready to insert the integrated circuits into their respective sockets. These need to be placed in the correct way, and there are two ways to identify them. Pin 1 is the top left leg of the IC—which is the rectangular black object in Photo 32. These legs are marked with a small dot in the top left corner or the upside of the IC is marked with a debossed half circle.
Step 17: Mounting and Final Soldering
PCB: Now for the real fun! We’re ready to start inserting chassis-mounted components. Let’s start with the populated PCB. Place the PCB with the three pots lining up with the drilled holes, place the pot washers on the shafts, and then tighten the pot nuts using a 10 mm (25/64") nut driver/wrench, for the results in Photo 33.
Footswitch: Now that the PCB is securely tightened, let’s go ahead and do the same for the footswitch. Remove all hardware from the footswitch bushing except for one nut and the lock washer (Photo 34).
Feed the footswitch through the footswitch hole, making sure that the footswitch has the two poles that we soldered together facing the bottom left (Photo 35).
Next, place the plastic washer onto the bushing (optional), and tighten the hex nut with a 14 mm (9/16") wrench (Photo 36).
Lets go ahead and solder the footswitch wires to their respective footswitch poles (Photo 37). See the instructions’ page 26 for pole-numbering reference.
Tip: Solder from the top row down—i.e. 1, 4, 7, then 2, 5, 8.Another tip: Remember that the wire for pole 4 also connects to pole 9.
Step 18: DC Jack
Next, we’ll need to solder the three wires that go to the DC jack, as explained in page 22 of the instructions. Start with the middle wire, since it sits the lowest and will be easier to get at without the other two wires in the way (Photo 38).
Step 19: Audio Jacks
The last chassis-mounted components are the two audio jacks. Let’s do the stereo input jack first. Go to page 24 of the instructions to see how these jacks are oriented. The lock washer goes on the bushing first, then gets placed into the hole to the left of the DC jack. Then, place the washer onto the bushing and tighten the hex nut with a 1/2" nut driver/wrench.
Follow the same steps for the mono output jack. And then, it’s the final soldering step: Solder the wires to the appropriate lugs on the audio jacks (Photo 39), as on instructions page 28. Then, finally, place the knobs on, tighten them down, and we’re done!
The third edition of Blackstar’s best-selling valve amplifier range.
In 2009 when the original HT Venue was designed the goal was to combine the best of our two flagship valve amp lines; the boutique cleans of the handwired Artisan amps and the modern high gain of Series One. This gave guitarists incredible flexibility of tone from a single valve amp, with no compromise between their clean and overdrive tones.
Seven years later Mk II introduced the most requested features; an expanded tone section on the Clean channel, footswitchable voices and power reduction.
A game-changing addition is their advanced CabRig DSP technology, an embodiment of our latest innovations in speaker, cab, mic, and room emulation. This technology, originally featured in our St. James and AMPED products, represents our commitment to staying ahead of the curve. Coupled with 4-channel audio via the USB-C, capturing professional quality valve tone in your DAW is simple.
The CabRig outs (XLR, Stereo Line Out and USB) can also be used in Standby Mode making it ideal for both recording and silent stages too.
Upgraded circuit board components and an all-new digital reverb with adjustable parameters further enhance the tone and performance.
All this comes in an all-new livery using materials normally found on boutique amps; premium tolex and fret, mini-toggle switches and a metal plate logo.
Blackstar’s new HT Venue MK III Series of guitar heads, combos and cabinets. Valve amps that are the culmination of decades of design experience and innovation; delivering “the sound in your head” with absolutely no compromises in tone, feel or performance.
